I am not buying too often. I bought some when I need to purchase miner, hyip and gambling. Now I buy some as I feel that price will go up. Will see how it will go.
Good luck to you and I commend you for buying bitcoins at the right timing, the price is low at the moment so there is a big chance that you will make profit in a short period of time but I am no God so only time will tell.
If you want to see real profits in it then hold it for long term, don't be worried about small fluctuations, as in long run price will be surely higher giving best returns on investments.
